RADIATOR.

Specification of Letters Patent. m t 'M' 11, 1919,

Application filed. January 16, 1918, Serial No. 212,040

To all whom it may concern:

Be it known that I, JOHN M. Fnnonns, citizen of the United States, residing in Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Radiators, of which the folsages through the several tubes;

The object of this invention is to provide improved means for increasing the radiation of the heat of the water to the air as the same passes through these tubes, which improvements are intended to simplify the construction, reduce the cost of manufacture and also increase the radiating efficiency of the radiator as a whole.

In the accompanying drawings:

Figure 1 is a front elevation, partly in section, of a radiating core embodying my improvements. Fig.2 is a longitudinal section taken in line 2-2, Fig. 1. Fig. 3 is a perspective View of one of the radiator sections forming part of the radiating means arranged in one of the air conduits. Fig. 4; is a similar view of one of the retaining members whereby a plurality of radiating sections are held in place Within one of the air tubes.

Similar characters of reference refer to like parts throughout the several views.

The body of the radiator-core with which my improvements are associated comprises a plurality of tubes which are arranged side by side and each of which is provided with enlarged end portions 1, 1, and a' contracted A central part 2. These tubes are preferably 1 constructed of sheetmetal and ofheiragonal form in cross section, althoughv the samegmay be otherwise constructed, ifdesired fInQassembling a plurality ofsuch tubes, thefacets of the large ends of.each tubeengage with corresponding facets of adj ac'ent. tubes so that the al enl em nt o the' stilbs form heads on opposite ,sicles offtheznadiator core while the spaces; betweenthecontracted central parts of adjacent tubes formlwater passages 3, 1 through which the ma ge the .1

can .7 I

engine to be cooled is circulated and" the atmospherepasses through the air conduits 4 formed by the bores of the several tubes. y Y

Inorderto increase the radiating capacity of these air tubes or; conduits, radiating means are arranged in each of these tubes which radiating means are preferably constructed as'follows: f y

Arranged in an annular row within each air tube is a plurality of radiating sections or members eachof which is preferably constructed of'sheet metal of substantially U shaped formin cross section and has its web 5 arranged innermost while its longitudinal flanges 6, 6 project outwardly fromopposite edges of the web, the arrangement of these flanges being substantially radial with reference to the axis of the air'tube in which the same are arranged. At its outer longiopposite ends of one of the aingtubes and an 3 intermediate receding edge portiom 8lrw hich engages with the bore of the contrac d cen tral part of the respective air, tube; ,.When a radiating section is thus ,engaged -with one of the air tubes, the enlargements at opposite ends of the flanges of theradiating section interlock with; the outwardly-facing shoulders formed, in the bore ,of the tive air tube between its enlarged end; parts a and its co ntracted central part so that )lohs nalid splaee ent of th s e t n s???- beis nae li 11 11- QIdP E 9 utilize th st l I Place ;t ust the. me i l, B its a s; f; the flanses n the e Pr du i g; U l

we e. ea iii s-s iieach of which engages an inner corner of the bore of one of the hexagonal air tubes and an equidistant arrangement of the flanges of the several radiating sections in each set is by this means obtained.

After a group or set of radiating sections has been thus introduced into one of the air 7 tubes, the same are held in place by a retaining sections. 'In assembling this radiating tube with a set of radiating sections, this retaining tube is first contracted so that the 'same will slip easily lengthwise into the space between the several radiating sections whichsurround the retaining tube and after this retaining tube has been fully inserted, the'same is ermitted to expand and engage its outer facets with the inner sides of the webs'of the respective set of radiating sections, whereby, the outward pressure of this retaining tube, due to its resilience, will cause the several radiating sections of this set to be pressed firmly outward and hold the outer edgesof the flanges of these radiat- "ing sections in reliable engagement with the bore of the respective-air tube.

[For the purpose of reducing the amount of'metal in the radiating means within each air tube, certain parts of its members may be perforated and stock removed where the same performs no useful function. For this purpose the webof each radiating section may be provided with openings 12 as shown in Fig. 3, and each of the retaining tubes may be provided with openings 13, as shown in Fig.4.

After the radiating means have been thus inserted in the air tubes and a plurality of such .tubes have been assembled to form the water passages between thesame, these assembled members are dipped-at their opposite ends into abath of solder, so as to connect the several air tubes with each other at their opposite ends and also connect each tube withthe radiating means therein, thereby completing the radiator core. I

In the completed radiator, means are provided for introducing'the water at one end of thew'ater conduits between the air tubes and withdrawing the same from the opposite end, this being accomplished in any suitable and mu; known manner. e V

These radiating means within the .air tubes are simple in constructiomthey can be easily made and assembled by the use of inexperienced help so that the cost of manufacture is reduced toa minimum. Furthermore, a

radiator thus constructed has an increased radiation effect, the same is materially strengthened and the same has an ornamental appearance when viewe'dfrom either side thereof. T

I claim as my invention:

. 1. A radiator comprising a tube, and radiating means arranged within said tube and comprising a plurality ofradiating sections arranged in an annular row and each being of U-shaped form in cross section and having its web innermost and its flanges proj ecting outwardly into engagement with the bore of said tube, and a retaining member engaging with the webs of said radiating sections.

' 2. A radiator comprising a tube, and radiating means arranged within said tube and comprising a plurality of radiating sections arranged in an annular row and' each being of U-shaped form in cross section and having its web innermostjand its flanges projecting outwardly into engagement with the bore of said tube, and a tubular retaining member engaging with the bores of the several radiating sections. v V

3. A radiator comprising a tube, and radiating means arranged in said tube and comprising a plurality of radiating sections ar-' ranged in an annular row within the tube, and a resilient tubular 7 retaining member which is split lengthwise and engages yieldingly with the inner sides of said'row of radiating members.

4. A radiator comprisinga tube, and radiatmg'means arranged within said tube and comprising a plurality of radiating sections arranged in an annular row and each being of u shaped formv in cross'section and having .itsweb' innermost and its flanges projecting outwardly into engagement with the bore of said tube, and provided at the outer edge ofe'ach flange with an inwardly projectinglip, and a retainingmember engaging 1lyith the webs of the several radiating memers. r
